CVE-2019-13300

ImageMagick versión 7.0.8-50 Q16 tiene un desbordamiento de búfer basado en memoria dinámica (heap) en MagickCore/statistic.c en EvaluateImages debido a la gestión incorrecta de las columnas.

A heap-based buffer overflow was discovered in ImageMagick in the way it applies a value with arithmetic, relational, or logical operators to an image due to mishandling columns. Applications compiled against ImageMagick libraries that accept untrustworthy images and use the evaluate-sequence option or function EvaluateImages may be vulnerable to this flaw. An attacker could abuse this flaw by providing a specially crafted image to make the application crash or potentially execute code.

ImageMagick is an image display and manipulation tool for the X Window System that can read and write multiple image formats. Issues addressed include buffer overflow, denial of service, double free, information leakage, null pointer, out of bounds read, out of bounds write, and use-after-free vulnerabilities.
